Baywatch teams up with the Coast Guard to search for a group of kids in the water. They all have to search in caves all they, but they still can't find all the kids. Allie is filming the caves with a camera with an infrared sensor to see what they have. When night falls, there's still two kids missing, but after watching over the film from their camera, they see what they think is a hand in one of the caves. They then decide to go out at night looking for the last ones, but soon discovers that the victims have been swept into another cave via an underwater channel.
